Debora Green (born Debora Jones, February 28, 1951) is an American physician who pleaded no contest to setting a 1995 fire which burned down her family's home and killed two of her children, and to poisoning her then-husband with ricin with the intention of causing his death. The case was sensational, and covered heavily by news media, especially in the Kansas-Missouri area, where the crimes occurred. Crime writer Ann Rule covered the case in her book Bitter Harvest. Though Green has claimed in recent years that her plea was placed during a period of diminished mental capacity, she has not been granted a new trial.
